| I deliver to a cyrus mailbox. If I have a "extension"
| (user+extension(_at_)domain) I want to use a different call to deliver than
| if there is no extension. The extension (and user) is passed to
| procmail in an environment variable. If there is no extension, then
| extension is either undefined or set to nothing (defined, but not
| value).
Just copy the pseudovamriable and make tests on the copy:
ARG = $1
:0
* ARG ?? [a-z]
{
# contains-letters
}
